Title: Drive circuit charge coupling element
Inventor: ITO TAKASHI
IPC: H04N5/335
Filed: 1986-11-05
Abstract: PURPOSE:To attain low power consumption without being attended with the deterioration in the transfer efficiency and signal charge by using a signal whose leading pulse value is highest of all the other signals so as to drive a series circuit cpeak omprising an inductance and a capacitance provided electrodes of a CCD. CONSTITUTION:Drive signals H1-H3 are impressed to each input of drivers 1-3, drive signal phi1, phi2 are impressed to electrodes phi11, phi12 of the CCD from the output of the drivers 1, 2 and the driver 1 receives power from the power supply 4 through all periods of charge transfer, pause and start. The output of the driver 3 at the start is boosted nearly up to a voltage V5 of the power supply 5 and the power voltage of the driver 2 is increased to a value V4+V5 by the bootstrap of a capacitor 6. Thus, the peak value of a drive signal impressed to the electrode phi12 of the CCD is increased by the driver 2. Thus, even if the energy of the resonance circuit is given, the peak value is not lowered than the normal value and the deterioration in the CCD transfer efficiency and the mixture of the transfer signal charge are not caused.

Filed: 1989-10-13
Abstract: PURPOSE: To form an insulator on the side wall of an opening on the surface of a substrate by using a pattern of a dielectric material having a thickness of <=1μm and a rectangular cross section. CONSTITUTION: The P area 51 of a silicon substrate 50 is formed by epitaxial growth and, on the area 51, a polysilicon layer 53 is formed on the first insulating layer 52. A silicon nitride layer 54 is formed in a chemical vapor-depositing atmosphere and an opening is formed by photolithography and etching. After the formation of the opening, a second conformal layer 55 is formed by chemical vapor-deposition. Then the pattern of a dielectric area 56 having a narrow width is established in an integrated circuit structure by exposing the polysilicon to an etchant and diffusion or ion implantation is performed by using the pattern as a mask. In addition, a conductive layer 57 is formed by reactive ion etching or wet chemical etching by using a plastic layer as a mask.  Finally, contacts 63 and 64 are formed in the P area 51 by flattening the conductive layer 57 with the plastic material, such as the photoresist, etc., and exposing the top section of the layer 57 in a reactive ion etching atmosphere, and then, removing the plastic layer by oxygen ashing. Thus an insulator is formed.
